Chapter 13, Problem 5PE

Program Plan Intro

Recursive Power Method

Program Plan:

• Global variable declaration:
  • Initialize the variable “minimum” as “1”.
  • Initialize the variable “maximum” as “100”.
• Define the “main()” function:
  • Initialize the variable “number” is “0”.
  • Initialize the variable “exp” is “0”.
  • Get the input from the user and store it to the variable “number”.
  • Check the value of “exp”
    • If it is less than “minimum” or greater than “maximum”, then get the exponent “exp” from user.
  • Call the function “recursivePower()” and pass the two arguments “number” and “exp”.
  • Display the result on the output screen.
• Define the “recursivePower(x, y)” function:
  • Check the value of “y”
    • If it is equal to “0”, then returns “1”.
    • Otherwise, call the function “recursivePower()” recursively along with the arguments “x” and the decremented value of “y”.
    • Display the result on the output screen.
• Call the “main()” function.
